is re-used. Use this mode to rapidly cool the inside of
the vehicle. The Recirculation mode can also be used
to temporarily block out outside odors, smoke, and
dust.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Automatic Temperature Control Ð If Equipped
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by a dual
sun-sensor in the top of the instrument panel, and an
infrared sensor located in the face of the control unit.
There are also various sensors monitored by this system
which take account for vehicle speed, A/C pressure,outside temperature, and engine cooling temperature.
The infrared sensor independently measures the surface
temperature of the driver and passenger. Based on the
sensor input, the system automatically adjusts the air
flow temperature, the air flow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple. Begin by turning
the right mode knob to AUTO, and place the blower
control (left knob) to either LO AUTO or HI AUTO. The

LO AUTO position should be used for front seat occu-
pants only. The HI AUTO position should be used when
more air flow is desired, or when rear seat occupants are
present. Dial in the temperature you would like the
system to maintain by rotating the driver's or passenger's
control knob. Once the comfort level is selected the
system will maintain that level automatically using the
heating system. Should the desired comfort level require
air conditioning, the system will automatically make the
adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely and closes the outside air intake.
72ÉF (22ÉC) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation.The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause an audible beep and the LED will flash three
times and remain off. This indicates that the system is in
AUTO and requesting the air conditioning is not neces-
sary.
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in recirculation mode
(ten minutes). This can be used when outside
conditions such as smoke, odors, dust, or high humidity
are present. This will cause an audible beep, and the LED
will illuminate. After ten minutes the system will return
to normal AUTO mode function and the LED will turn
off.

NOTE:
²
The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor's location.
Mud on the windshield may also cause poor operation
of this system.
²To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
²Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
Manual Operation
This system offers a full complement of manual override
features which consist of Blower Preferred Automatic,
Mode Preferred Automatic, or Blower and Mode Pre-
ferred Automatic. This means the customer can override
the blower, the mode, or both. There is a manual blower
range used when the AUTO setting is not desired. The
left control can be set to any fixed blower speed by
rotating the knob.
NOTE:Please read the Automatic Temperature Control

ON. The defroster automatically turns off after approxi-
mately 10 minutes of operation for the first push of the
button, and will turn off after approximately 5 minutes
for the second push of the button.
CAUTION!
To avoid damaging the electrical conductors of the
rear window defroster, do not use scrapers, sharp
instruments, or abrasive window cleaners on the
interior surface of the window.
Labels can be peeled off after soaking with warm
water.
This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The recirculation mode should only
be used temporarily. The button includes an
LED that illuminates, and an audible beep indicates that
the recirculation mode is active. You may use this feature
separately.
NOTE:Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the ªRecirculateº icon button to return to
outside air. Some temp./humidity conditions will cause
captured interior air to condense on windows and ham-
per visibility. For this reason, the system will not allow
ªRecirculateº to be selected while in the defrost or
defrost/floor modes. Attempting to use the recirculation
while in these modes will cause the LED in the button to
blink and then turn off.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.

Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
NOTE:See Operating Tips chart (for Manual A/C
Control) at the end of this section for suggested control
settings in different weather conditions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow and if they
enter the plenum they could plug the water drains. In
winter months make sure the air intake is clear of ice,
slush and snow.
A/C Air Filter Ð If Equipped
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to ªMaintenance Proceduresº in
your Owner's Manual for filter replacement instructions.

NOTE:
²
The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1±3 miles (1.6±4.8 km) of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into ªOverdriveº when cold. This is
considered a normal condition. Pulling the shift lever
into the ª3º position will show that the transmission is
able to shift into and out of ªOverdrive.º
²If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. Park (P), Reverse (R), and Neutral (N) will
continue to operate. This Reset feature allows the vehicle
to be driven to a dealer for service without damaging the
transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
²Stop the vehicle and shift into PARK (P).
²Turn the key to LOCK then start the engine.
²Shift into ªDº and resume driving.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.

Neutral
No power is transmitted from the engine to the drive
axle. When the brakes are released, the vehicle can be
moved freely (pushed or towed). Do not engage in
NEUTRAL position while driving except to coast when
the vehicle is in danger of skidding (e.g., on icy roads).
The engine may be started in this range. Use this range
for starting your vehicle if it is moving or being towed.
CAUTION!
Coasting the vehicle, or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage that is not covered by the Limited
Warranty.
Drive
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts and best fuel economy.The transmission automatically upshifts through fifth
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers, use the AutoStick mode and select the ª3º range.
AutoSticktGear selection
The transmission gear can be selected by pressing the
selector lever to the right or the left with the selector lever
in the DRIVE position. The gear currently selected is
indicated in the instrument cluster display. Briefly press
selector lever in the ªD -º direction. The transmission will
shift from the current gear to the next lower gear. Shifting
into another gear that allows for quicker acceleration or
to slow the vehicle down is possible. Downshifts can also
be performed.
Press and hold the selector lever in the ªD-º direction.
The transmission will shift from the current gear directly
to the best gear for acceleration.
216 STARTING AND OPERATING
ProCarManuals.com

NOTE:To avoid overrevving the engine when the
selector lever is moved in ªD -º direction, the transmis-
sion will not shift to a lower gear if the engine's revolu-
tions per minute limit would be exceeded.
Briefly press the selector lever in the ªD +º direction. The
transmission will shift from the current gear to the next
higher gear.
Press and hold the selector lever in the ªD +º direction.
The transmission will shift from the current gear directly
to gear ªDº.
WARNING!
On slippery road surfaces, never downshift in order
to obtain braking action. This could result in drive
wheel slip and reduced vehicle control. Your vehi-
cle's ABS will not prevent this type of loss of control.
You could lose control of your vehicle and have an
accident.
Delayed Shifts in Cold Temperatures
During cold temperature operation you may notice de-
layed upshifts depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency.
Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens, or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped,
PARK(P), REVERSE(R), and NEUTRAL(N) will continue
to operate. SECOND gear will operate in the DRIVE(D)
shifter position. The Malfunction Indicator Lamp may be
illuminated.

WARNING!
Connecting trailer brakes to your vehicle's hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
²Do not attempt to tow a trailer while using a compact
spare tire.
²Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
recommended for motoring safety.
²The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more
than 45 minutes of continuous operation. See Schedule
ªBº in section 8 of this manual for transmission fluid
change intervals.
NOTE:
²
For vehicles equipped with Autostick. By using the
Autostick modes, and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
performance. For example, choose ª4º if the desired
speed can be maintained. Choose ª3º or ª2º if needed
to maintain the desired speed.
²Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
